Comments:For a stand to be classified as a member of the mixed oak series, no single oak can dominate. Stands dominated by a single oak species are assigned to other series [ see Black oak series, Blue oak series, Interior live oak series, Valley oak series].
Plot based descriptions:Allen et al. (1989, 1991), define 11 Mixed oak subseries, based on tree and shrub data in Cis-CA. These subseries are called associations here. Jimerson (1993) defines two associations in o-NorCo.
Series Association:Allen et al. (1991): Black oak-valley oak/grass association, Blue oak-valley oak-coast live oak/grass association, Interior live oak/toyon association, Mixed oak-black oak/grass association, Mixed oak-California buckeye/grass association, Mixed oak-coast live oak/poison-oak association, Mixed oak-foothill pine/grass association, Mixed oak/grass association, Mixed oak-interior live oak-foothill pine association, Mixed oak/poison-oak - coyote brush association, Mixed oak-valley oak/poison-oak - California coffeeberry association.
